Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a jig for fastening a tightening band, and more specifically, for use in attaching a boot to the upper support part of an automobile suspension. The present invention relates to a jig for fixing a loop-shaped tightening band used when connecting and fixing a cylindrical body made of rubber or the like to a tube body.

(Prior Art) Conventionally, to fasten such a tightening band, a screwdriver, pliers, etc. have been used (see Japanese Patent Publication No. 51-9930 or Japanese Utility Model Publication No. 59-88591).

That is, as shown in FIG. 5, the tightening band 1 is wound in a loop around the rubber boot 3 that is inserted outside the tube body 2, and the other end is inserted through the guide 4 provided at one end of the tightening band 1. After temporarily tightening the belt, the hook-shaped ends 6 and 7 of the yatsutoko 5 were hooked onto the protrusions 8 for tightening operation provided on both ends of the tightening band 1 to tighten the tightening band 1. . Then, as shown in FIG.
By fitting the guide 4 into the guide 4 and caulking the guide 4, the tightening band 1 was fixed in the tightened state described above.

(Problem to be solved by the invention) However, since the tube body 2 and the rubber boots 3 mentioned above usually have a diameter larger than a certain degree, the Yatsutoko 5 is also a relatively large one that requires both hands to open and close. will be used. Therefore, since both hands are occupied by the operator 5, another worker must be assigned to align the claw 9 and the fitting hole 10 in the tightened tightening band 1 and to fit them together. The badness of it was hot.

In addition, it requires considerable physical strength to operate Yatsutoko 5,
Moreover, it is troublesome that the claw 9 and the fitting hole 10 must be aligned by adjusting the degree of opening and closing.

Accordingly, the technical problem to be solved by the present invention is to enable a single worker to easily and quickly perform the fastening work of the tightening band.

(Means for solving the problem) A technical means for solving the above problem is to have inner and outer ends wrapped in a loop around the tightening body and overlapped with each other, and the inner end The part has one convex part with a hole for tightening operation and multiple claws cut and raised backwards at the same interval on the tip side, while the outer end has a convex part with a hole for tightening operation. When the parts and the fitting holes are provided alternately and at intervals such that the claws fit into the fitting holes, and the distance between the convex part with a hole at the inner end and the outer end is width α, the claws is a jig for tightening and fixing a tightening band aligned with any of the fitting holes to the tightening body, the jig being a jig for tightening and securing a tightening band to the tightening body, which is located on the opposite proximal side of a rod-shaped handle whose proximal side is a grip. A base portion of an arm formed longer than the predetermined length by a predetermined width α is pivotally attached to a portion closer to the proximal end by a predetermined length from the tip, and the handle and the arm are biased in a closing direction. and a hook is provided at the tip of the handle to be hooked to a convex portion with a hole on the inside of the tightening band, and a hook is provided at the tip of the arm to be hooked to a convex portion with a hole on the outside of the tightening band. It is characterized by the provision of a hook.

(Function) The handle and arm are opened at a required angle, and each hook at the tip of the handle and arm is tightened by the tightening convex on both ends of the tightening band. Hang them on each section.

Next, when the handle is tilted in the opposite direction to the opening direction of the arm, the arm is also pulled in that direction and the tightening band is tightened.

When the handle is tilted down to the tangent to the loop-shaped tightening band, the handle and the arm overlap in parallel, and the distance between their tips matches the predetermined width α. At this time, the fastening claws provided at predetermined positions on both ends of the tightening band and the fitting holes are aligned.

(Example) Next, an example of the present invention will be described based on FIGS. 1 to 4.

As shown in FIG. 1, the attachment jig 11 consists of a rod-shaped handle 12 and an arm 13.

A grip 14 is provided on the proximal side of the handle 12, and a stepped hook 15 is formed at the distal end on the opposite proximal side.

The arm 13 is a channel-shaped bar with a U-shaped cross section, pivotally attached by a pin 16 to a portion of the handle 12 a predetermined length A away from the tip of the handle 12 toward the base end, and is designed to overlap parallel to the handle 12 when the handle 12 is stored in the groove of the channel-shaped bar, as shown by the imaginary line in Fig. 1. The arm 13 is provided at its tip with a hook-shaped hook 17 that faces the stepped hook 15.

Further, the arm 13 has a predetermined width α from the length A.
It has been formed for a long time. This width α is a width set in advance in correspondence with a tightening band 24, which will be described later.

Next, between the handle 12 and the arm 13,
As shown in FIG. 1, a coiled spring 18 is provided. This coiled spring 18 has a central pair of coil parts wound around the pin 16, and of biasing arm parts 19 and 20 connecting the pair of coil parts, one is attached to the handle 12 and the other is attached to the arm. 13 in the compressed state of the coil spring 18, and the handle 12 and the arm 13 are brought into close contact with each other (in the first direction).
The state shown by the imaginary line in the figure is energized.

The fixing jig 11 configured as described above is used as follows.

In the upper support part of the automobile suspension shown in FIG. 2, a ring-shaped bracket 21 provided at the upper end side of the shock absorber has
A rubber bellows-shaped boot 22 serving as a tightening body is inserted. A tightening band 24 is fitted in a loop shape into an annular groove 23 provided on the outer periphery of the boot 22 and fixed thereto.

This tightening band 24 is formed using a long and thin strip-shaped steel material, etc., and as shown in FIG. The other end, which overlaps the outer surface of the end, is provided with a plurality of protrusions 26 with holes for tightening operation provided at predetermined intervals. In addition, a plurality of convex portions 2
A plurality of fitting holes 27 are formed at the end portion where the projections 26 are provided, and the fitting holes 27 are arranged alternately with the projections 26 .

On the other hand, at the end where the single convex portion 25 is provided,
At a position closer to the tip than the convex portion 25, with the same spacing as the mutual spacing of the plurality of fitting holes 27,
A plurality of claws 28 protruding toward the outer circumferential side are cut and raised rearward. When both ends of the tightening band 24 are placed facing each other as shown in FIG. At this time, the claw 28 is aligned with any fitting hole 27. Note that a known guide and fastening member 29 is attached to one end side of the tightening band 24.

As shown in FIG. 2, the above-mentioned tightening band 24 is wound along the groove 23 of the boot 22, and as shown in FIG. 3, one end thereof (the end where the fitting hole 27 is provided) is placed on top of the other end, and the hook 17 provided on the arm 13 of the fixing jig 11 is hooked onto an arbitrary convex portion 26, and the arm 13 and the handle 12 are connected against the biasing force of the coil spring 18. Open the angle and hook the stepped hook 15 to the convex portion 25. The convex portion 26 on which the hook 17 is to be hooked can be selected depending on the required tightening width of the tightening band 24. The stepped hook 15 of the fastening jig 11 assembled to the tightening band 24 in this way
and hook 17 do not come off from the protrusions 25 and 26, respectively, due to the biasing force of the coiled spring 18. Therefore, the above operations can be performed with one hand by grasping the handle 12.

Next, grasp the grip 14 of the handle 12 and tilt the handle 12 in the direction opposite to the opening direction of the arm 13 (in the direction of arrow B in FIG. 3). Then, since the pin 16, which is the fulcrum of the arm 13, also moves in that direction, the arm 13 is pulled, and the tightening band 24 is tightened accordingly. At this time, the operating force acts on the grip 14 at the upper end of the handle 12, so a small operating force can generate a large tensile force on the arm 13, making the operation easy.
Furthermore, since the above operations can be performed with one hand, the worker can support the top support portion, prevent the tightening band 24 from slipping, etc. with one hand.

As shown in FIG. 4, when the handle 12 is brought down to a tangent to the loop-shaped tightening band 24, the handle 12 and the arm 13 overlap in parallel, so that the distance between the stepped hook 15 and the hook 17, in other words, Then, the convex parts 2 on both ends where these hooks are hooked
The interval between 5 and 26 corresponds to the predetermined width α. Therefore, the fitting hole 27 and the claw 28 are automatically aligned, so that they are fitted together as is. Thereafter, the guide and fastening member 29 is caulked and the end of the tightening band 24 is pressed down, thereby completing the fastening of the tightening band 24.

Incidentally, since the stepped hook 15 having the illustrated shape can be easily removed from the convex portion 25, the attachment jig 11 can be easily removed after the operation is completed.

In the present invention, the coiled spring 18 described above can be replaced with other known biasing means capable of biasing the handle 12 and the arm 13 in the direction of closing each other.

(Effects of the invention) According to the invention, the fastening operation of the tightening band can be easily and quickly performed by one worker, and with a small operating force.

That is, in the present invention, by providing a means between the handle and the arm to bias them in the closing direction, the handle and the arm are attached to the convex part for the tightening operation at each end of the looped tightening band. When tightening the tightening band by hooking each hook, the handle does not inadvertently rotate with respect to the arm, and the tightening band can be tightened with one hand. In addition, in the present invention, the base of the arm, which is formed to be longer than the predetermined length by a predetermined width α, is pivotally attached to a portion closer to the proximal end by a predetermined length from the distal end, so that the handle and the hooks at each end of the arm can be tightened. After hooking the attached band onto the convex part for tightening operation at each end, hold the handle grip with one hand and tilt the handle in the direction of closing the arm.The handle and arm will easily become parallel (both tightening). Since the distance between the protrusions for attaching operation is α, the fitting holes of the tightening band and the claws fit together, and the tightening band can be fixedly attached to the tightening body in a tightened state.
